BASE FOR STEREOTYPE-PLATES.

SPECIFICATION forming part of Letters Patent No. 360,307, dated March 29, 1887.

Application filed March 11, 1886. Serial No. lfidjlli.

T0 aZZ whom, it may concern.-

Be it known that I, LOUIS KLOPSOH, of New York city,in the county and State ofNew York, have invented a certain Improvement in Bases for StereotypePlates, of which the following isa specification.

The improvement is intended more particularly for serving with plates of celluloid or analogous tough and durable material of such light weight as to render practicable their transmission to distant points by mail; but it may serve with great advantage with typeme-tal or any other stereotype.

I use the term stereotypes to indicate plates of any material adapted to be printed from, andof such thickness or height as to require to be supported on bases in order to render them type-high. The supports or bases may obviously be of any weight and cost, as one set of bases may serve with a great number of different plates successively applied and removed.

In order to facilitate the fastening of the plate to the base, I provide grooves on the up per side of the base and secure therein a ma terialas soft metal or wood, or bothadapted to receive and hold nails; and I.indieate on the plate by a series of indentations or depressions the location of these grooves thus filled. Nails driven through at these points will find in the base suitable material to receive and hold them, while the adjacent portion of the base will serve to efficiently support theplate without being anywise disturbed or distorted by the operation.

In what I consider the best means of carrying out the invention I produce the body of the base or support in cast-iron, and after finishing it to proper size plane longitudinal and transverse grooves in it of dovetail section. In each longitudinal groove I afterward hold a stick of wood of smaller section and pour in melted lead to fill the space'between. This affords a very desirable construction for receiving and holding the nails. I also provide for further locking the lead in the base by allowing it to fiow into holes drilled or otherwise produced transversely to the groove.

The accompanying drawings form a part of this specification and represent what I consider the bestmeans of carrying out the invention.

Similar. letters of reference indicate corre sponding parts in all the figures where they occur.

A is the hard portion or main body of the base. It is of proper height to hold the printing-surface of the stereotypeplatc B typehigh. In each face are three longitudinal grooves or scores, a a a, and through its substance are a series of holes, a it, across the grooves a a, and communicating with each. There are also a series of corresponding transverse grooves, ck. The grooves a and 0t are filled with soft material. The holes aare also filled or partly filled, as will presently be explained. They are serviceable in allowing the soft material to flow out into them and form arms which lock the soft material in the base.

O G are column-rules.

D D are nails driven through the plate B into the soft material M in the grooves a a a.

To make the base, east the main body A of rectangular section, and plane or mill it to the exact form and size required. At the same or a subsequent operation, as by treatment by a suitable planer, produce the longitudinal dovetail grooves a a a. Either before or after this, drill the crossholes a. Then, carrying each base separately or a number together mounted transversely on the planer-table, produce a series of corresponding transverse grooves, a Then, after heating the part A nearly to the temperature of melted lead, hold in suitable close-fitting metal clamps and introduce in each groove a smaller stick of soft wood, P, and, holding it in place by means analogous to the chaplets used to hold cores in place in iron casting, pour in melted lead to fill the space around and over each stick. This operation fills the grooves a a a with wood, P, and lead,M, and the transverse grooves a with lead, M alone. It also fills the whole or a portion ICO of each hole a with lead, forming in each an arm, lllflcast in one with the lead, M. There should be a surplus of lead. When all is cooled, use a shaving-machine to remove such lead as is in excess of the requirements, and which cannot be readily otherwise removed with suffiany burrs which the insertion and withdraw ing of the nails may have raised.

The entire base may be reversed and either face used uppermost. This allows the nails to be driven and withdrawn many times before the soft material is seriously damaged.

At long intervals the whole base may be put in the melting-pot and the lead melted out, after which it may be refilled, using the same lead and either the same or new wood. will again serve as before. The sticks can be omitted, if preferred, and the lead, M, may entirely fill each groove. Nails can be easily .driven into lead and will hold well therein.

The lead is retentive, and a small number of nails will hold large surfaces of stereotypeplates.

In applying the parts together and fastening them, the column-rules O G are of service in holding the plates exactly in position. The nails D may be driven in the usual manner.

Screws or other like fastenings may be used in place of nails D, if preferred.

' Modifications maybe made in the forms and proportions of the base without departing from the principle or sacrificing the advantages of the invention. Two grooves a, or even one, may serve instead of three. Four ora larger number may be used. They may be made on one face only of the base; but in such case the base will not be reversible. If only one groove is used, it should extend along the middle of the column. The grooves may run longitudinally alone or transversely alone. Other soft metal than lead may be used. The grooves may be of rectangular section instead of dovetailed,depending on the engagement of liably without the arms M engaging in the holes a. lVood alone or certain gums maybe used with some success for the soft material in the grooves. In such cases pins of hard wood or other strong material should be driven transversely through the holes a.

The holes a may be only partly filled in consequence of the lead chilling if the bases are not sufficiently warmed. It is sufficient if thelead flows into the hole only a little way. I prefer the whole as first described.

It will be observed that I do not intend to embrace within this case a construction for bases for stereotype-plates where a metallic support is providedwith parallel rabbets into which are introduced removable strips of wood or othersoft material in such a manner that the upper surfaces of the wooden strips may be on a level with the upper surface of the support and the stereotype-plates are secured to, the wooden strips, since this construction has been made the subject of a separate application by me for Letters Patent, filed December 7, 1885, Serial No. 184,892.

I claim as my invention- 1. A stereotype-plate, B, hard supportingbase A, and nails or equivalent fastenings D,in combination with each other and with a filling, M, of soft materiahand locking-arms M, fitting in corresponding recesses in the base, as herein specified.

2. The wood strip P, lead envelope M, and lockingarms M, in combination with each other and with a correspondingly-recessed hard base, A, adapted to serve with a stereotypeplate, B, and nails D, as herein specified.

3. Alongitudinal softmaterial, M, in combination with the transverse soft material M hard base A, plate B, nails D, and means,as the locking-arms M, for confining the filling in the base, as herein specified.

In testimony whereof I have hereunto set my hand, at New York city, New York, this 5th day of March, 1886, in the presence of two subscribing witnesses. I
